About this 1.35ct lab-grown cushion diamond

This 1.35ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG735554276 or 735554276. Listed at 19 retailers as of October 30, 2026, with prices from £172 to £908, a £736 spread on the same certified stone. Reve Diamonds lists it at £908. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
